Could Microsoft revive windows phone?

Yes I was talking of Lumias. And no phone was released by Microsoft or any other OEM with the Creators update in 2017

If Microsoft had released just 1 Lumia with Continuum with each of Anniversary update & Creators update, Windows phones would have been very much alive today

For someone who touted markets outside the US as being essential to W10M's survival it's interesting that you failed to mention that there WAS a Windows phone released in 2017 - the Wileyfox Pro. Face it, you're a Lumia fan and not much else matters when it comes to Windows.

In my experience with Windows mobile, through 8, 8.1, and 10, I found the os buggier by far than the Android competition. Honestly I couldn't wait to get back to Android. You can get some seriously good Android devices for some very good prices........ I think WP failed because they got beat in the marketplace plain and simple.

Having live tiles, which is what most folks seem to like about WP (including me) isn't on it's own enough to make a market beating phone. WP wasn't good enough to survive so it didn't.

I am very curious to see what they bring out next though..... and am willing to give it a try if it looks to have potential ;-)
